Never complain and never explain.
Be thine own palace, or the world's thy jail.
Things do not happen. Things are made to happen.
Expect problems and eat them for breakfast.

Be gentle to all and stern with yourself.
The secret of getting ahead is getting started.
Begin to be now what you will be hereafter.
